accordian Posted December 2, 2018 Share Posted December 2, 2018 Thought Id have a go at repairing my old 1 row melodeon. One of The bass notes needed more Effort to get it to make a sound so I gently bent the reed back into its position so that the space between the reed and the air chamber is less. That worked however another problem with one of the reeds is that it make a rattling noise. The rattle sound is made on the opening of the bellows. What do you think? My guess is that the reed is hitting the reed frame if. This is what is happening what would be the correct method to fix it? Thanks Link to comment Share on other sites More sharing options...
Chris Ghent Posted December 2, 2018 Share Posted December 2, 2018 Temporarily tape the valve next to the reed shut with a tiny scrap of the weakest tape you can find. If the noise disappears replace the valve. Link to comment Share on other sites More sharing options...
saguaro_squeezer Posted December 3, 2018 Share Posted December 3, 2018 I get that noise when the reed frame is under pressure. Link to comment Share on other sites More sharing options...

That‘s what I experienced too once - very different from a tired valve soundwise - but it was a (too quality) concertina reed, with a very tight fit, wouldn’t think it could happen that easily with an accordion (melodeon) reed...

saguaro_squeezer Posted December 3, 2018 Share Posted December 3, 2018 Wolf, I get it often enough since I live in the desert SW of the US. There's always a bit of adjustment when a concertina comes over and dries out a bit. Depending on the quality, sometimes only one reed. The 50s Wheatstone 1T that I just bought has had most of the adjustments ... but it weighs very little so I expect that the wood is lighter.

Wolf Molkentin Posted December 3, 2018 Share Posted December 3, 2018 in addition to lighter wood it might have alloy reed shoes, another factor re little weight Link to comment Share on other sites More sharing options...
accordian Posted December 4, 2018 Author Share Posted December 4, 2018 if it makes any difference the reeds are made of brass Link to comment Share on other sites More sharing options...
Wolf Molkentin Posted December 4, 2018 Share Posted December 4, 2018 so they‘re supposed to be difficult to bend - maybe you‘ve overdone it? Link to comment Share on other sites More sharing options...
Theo Posted December 5, 2018 Share Posted December 5, 2018 I repair lots of old Hohners and this sort of rattle is a fairly common problem on basses. It's almost always caused by the reed tongue hitting the frame. This can either be a burr on the edge of the reed tongue, a burr on the edge of the reed plate vent, or a spot of corrosion on the side of the reed plate vent if it is zinc. If it happens on opening the bellows then it is the hidden reed under the reed plate that you need to work on. It can also be the reed tongue off-centre.
